Double Sérum Thérapiste

Dual-serum for both fine and thick hair. Ends renewal care.

Double Sérum Thérapiste

Doubly effective, this product combines an oil-based care agent, which has the particular quality of being able to very delicately moisturize the fiber, with a denser, cream-textured top-coat to treat and seal ends. A subtle mix of compounds that are highly cutting-edge but contradictory in terms of formulation, this product offers unique results. Third performance factor: the fibers are thermo-protected when using heated styling tools at temperatures of up to 230°C / 446°F. A finish that is immediately noticeable by everyone, an extra dose of softness as a final touch.

Rated 5 out of 5 by from Amazing! Sounds strange but I feel joy as soon as I put this product in my wet hair. It smells amazing! My husband keeps telling me how great my hair smells too. It makes my hair feel like silk and I swear after a month of using this product my hair not only looks healthier, shinier, but it feels silky and stronger than it has.

Rated 4 out of 5 by from Real Deal I had gotten shingles a few years ago, on my face & scalp. It was terrible; My hair was falling out, when I had to use my flat iron on my hair that was quite literally breaking of by my bangs to the point where friends & family thought I had been cutting it off it was so bad. My stylist recommended this product to me, I had never used Kerastase before. It's pretty pricey..but two months of using this and my hair was unbelievably imptoving. I've ordered this dual serum many times, I've tried almost all the brands out there, from high end to low end. Literally. Every. Brand. Almost..and NONE of them even came somewhat close to the drastic improvement I continue to see in my hair. Honestly, this stuff saved me. Only 4 stars though, simply because there should absolutely be a larger amount than the almost pocket-sized 30 ML amount that it comes in for the price it:s sold for.

Rated 5 out of 5 by from Smells Great! I know many people don't like the fresh smell of this product but it is amazing. My family always complains when I switch to the other high end brands that smell like sweet icky candy or "dirty". Maybe try the Elixir oil, which has a "warmer" smell instead. I am still irritated about the packaging though.

Rated 4 out of 5 by from I liked this.....I’d like more. I’ve had mine for a month now, and this helps. I have 49 yo rather pathetic hair. It is colored and highlighted to hide all the grey. It falls out and regrows, so I have millions of baby hair flyaways. This product combination helps. I actually love the smell. It is better than Oribe Gold Lust, in my opinion. It also protects from heat better than my Gold Lust serum. My hair is silky and soft and the smell matches the texture; silky and soft. It does not smell like fake fruit or fake floral like so many other products. My husband loves it. I do wish there was more of it. It is expensive to the point of annoying for the amount in the bottle. I don’t mind spending money for great products, but I also do not appreciate being duped. Like other reviewers, I would not mind these two products to be sold separately to combine them myself. Or, just three times the amount of product for the money.

Rated 3 out of 5 by from Not enough product in a bottle I love how this product can change my hair, more specifically the oily part of the serum. I also love the smell, as my hair smells wonderful for days when I use it. On the other hand, I just can't stand the design of the bottle because the real amount of product in it is really outrageous. I wish I could buy a big bottle of the oily serum. Unfortunately, I will have to find another product that can actually last.
